The present invention relates to improvements in tobacco pipes through which the smoke has to travel a relatively longer way than in ordinary pipes, before reaching the mouth which particularity provides for cooling of the smoke and the separation of the nicotine, the bottom of the bowl being fitted with a coollecting reservoir for the nicotine.

Other features of the improvements will appear through the following description; it

will be seen that the normal outer appearance of the pipe is maintained.

The invention can be applied to straight or curved pipes, as well as to cigaretteor.

' cigar-holders.

The invention 1s hereafter described and illustrated in the accompanying drawings,

given merely by way of example.

Fig. 1 is an axial longitudinal sectional view of a curved pipe; 1

Fig. 2 is a transverse sectional view along A-B of Fig. 1.

With reference to these figures, the pipe is formed, as usual, of two different parts, one of which comprises the bowl and stem 5, and the other one the mouthpiece 8, both parts being removably assembled to each other by suitable means.

In the bottom of the hollow part 3 of the so bowl is formed a small reservoir 4, for collecting the nicotine; said reservoir is separated from the bowl 3 by a grating or plug 1 provided with one or several holes 6 extending vertically throughout. This plug is made of metal, wood or meerschaum and can be removed for its cleaning or for cleaning the pipe.

Near the plug 1 and immediately above the nicotine collector 4, starts a lateral smoke channel 2 extending longitudinally along the whole length of the stem 5 of the pipe, up to the mouthpiece 8. Parallel to this smoke channel 2, another smoke channel 10 is bored, which is blind at the front part and of a larger cross sectional area than the first channel 2. The entrance to this second smoke channel 10 is threaded for receiving a screw 11, which is screwed or keyed in the mouthpiece 8. This screw 11 is hollow at its middle and connected, on the one hand to the-channel 12 of the mouthpiece 8, and on the other hand, to the second smoke channel 10 of the stem 5. The smoke channel 2 is connected to the second smoke channel 10 by a groove 7 formed at the stern end of the stem, and a bore 9, inclined with respect to the pipe axis, starting at said groove 7 and having its opposite end communicatin with the front portion of said second smo e channel 10.

The smoke coming from the'bowl, through section, passes through the lateral smoke channel 2, the groove 7, the slot 9, the channel 10,the bore of the'screw l1 and the channel 12, following the direction of the arrows in Fig. 1. This prolonged travel brings about an intensive'cooling of the smoke as well as the deposit of the nicotine inside the'reservoir 4. I I Thecleaning' of the various channels an passages can be effected without any difiiculty and in the same way as for ordinary pipes.

The independent elements can be made of metal, wood or any suitable material commonly employed in the tobacco pipe fabrication. The bowl and stem may be made of wood, meerschaum or any other suitable material and the mouthpiece 8 may be made of inlnber, imitated amber, horn, ebonite and the It will be understood that all the improvements according to the invention being internal, the outer aspect of the pipe is not changed in the least. The pipe can be provided with the usual protecting cover or stopper.

It must be noticed that the bowl and stem of the pipe do not comprise any independent element, except the plug 1, the channels being bored and the grooves being formed di rectly into the material of the pipe. pipe has thus, a great solidity and its manufacture is very simple, while it is at the same time as hygienic as possible. The tobacco can be completely smoked, owing to the plugged bottom 1, and the smoke reaches the mouth, cooled and completely freed from nicotine.

I claim; 1. In a tobacco pipe of normal shape, a cooling and purifying device comprising in combination: a removable perforated plug 1 The v necting said transverse groove and the front located within the bottom of the bowl and upon which rests tobacco, a reservoir formed by a downward extension of the hollow part of the bowl for nicotine deposit, a lateral smoke channel bored into the stem, a transverse groove formed inside the stem and near the stern end of it, a second smoke channel of a suitably larger cross sectional area bored longitudinally in and centrally to the stem, a sloping slot formed in the stem for conportion of'said second smoke hannel.

2. In a tobacco pipe of normal shape, a cooling and purifying device comprising in combination: a removable perforated plug located within the bottom of the bowl and upon which rests tobacco, a reservoir formed by a downward extension of the hollow part of the bowl for nicotine deposit, a lateral smoke channel bored into the stem, a transverse groove formed inside the stem and near the stern end of it, a second smoke channel of a suitably larger cross sectional area bored longitudinally in and centrally to thestem,

a sloping slotformed in the stem for connect ing said transverse groove and the front portion of said second. smoke channel, a mouthpiece having a bore, a screwing device forming part of the mouthpiece, centrally bored for suitably connecting said bored mouthpiece to the second smoke channel.

In testimony whereof I hereunto sign my 7 name.
